Question

Hi guys,
I have an app that send some notification e-mails for myself using Mandrillapp's SMTP server. It works fine on my localhost/development, but in DigitalOcean's Droplet I get an PHP exception telling me that the connection have timed out.

Using Netcat I would be able to confirm this:

nc: connect to smtp.mandrillapp.com port 587 (tcp) failed: Connection timed out

It's possible to have this working on DigitalOcean or I need to do something else to send e-mails?

Thank you!

Droplet: Ubuntu 14.04 (LAMP Stack)

telnet smtp.mandrillapp.com 587
Trying 54.184.79.59...
Connected to smtp.mandrillapp.com.
Escape character is '^]'.
220 smtp.mandrillapp.com ESMTP

As you can see, it is working for me. what firewall rules do you have configured?

In order to curb spam and abuse, some new user accounts have their SMTP ports blocked by default. This is automated, and unfortunately there are sometimes false positives. If the above command does not work for you, it's likely that this is what's going on. Open a support ticket, the team would be happy to remove that block for you.
